  • Patent number: 11373020
    Abstract: Systems and methods are provided for developing and producing a die using mesh data. A mesh data file representing a surface of the die is created. The mesh data file is configured in an original format that is one of a point-facet format or a node-element format. The mesh data file is translated into a translated format that is another of the point-facet format or the node-element format. Prior to building, the die, as represented by the mesh data file, is evaluated virtually.

  • Patent number: 11370435
    Abstract: A method for controlling automated driving operations of a vehicle includes determining vehicle origin and destination data, and generating a graphical representation of a road network with multiple candidate routes between the vehicle's origin and destination. Road-level data, including speed, turn angle, and/or gradient data, is received for each candidate route, and respective total energy uses are estimated for the vehicle to traverse across the candidate routes. Multiple candidate driving strategies, each having respective speed and acceleration profiles, are determined for the candidate route with the lowest estimated total energy use. An optimal candidate driving strategy is selected through a cost evaluation of the associated speed and acceleration profiles and forward movement simulations of the vehicle over a prediction horizon.
